With over 15 years working in the hydrogeology realm, and 5 years managing the Aquifer Mapping Program, Stacy has enjoyed working all around the desert southwest and New Mexico. Developing regional scale hydrogeology projects to address important societal questions or issues has been the emphasis of Stacy's work at the Bureau. However, she really enjoys the process of helping people understand their water resources, especially groundwater. Stacy began serving as an Associate Director for Hydrogeology Programs at the Bureau in 2019, and has added the responsibility of leading the implementation of the NM Water Data Act (from 2019 House Bill 651). Stacy has worked in hydrogeology for the Bureau of Geology since 2004.
